State Street Corporation's (NYSE:STT) SPDR Portfolio S&P 500 ETF (NYSEARCA:SPYM) has experienced a significant surge in assets under management, rising by approximately $18.3 billion since March 31, 2026, according to company data. This growth is largely attributed to the fund's selection as the default investment vehicle for the newly launched Trump Accounts, a government-sponsored savings program for children.
The Trump Accounts initiative, announced by the Treasury Department, automatically directs all initial contributions into SPYM unless account holders actively choose an alternative provider. Each child born between January 1, 2025, and December 31, 2028, who is a U.S. citizen, qualifies for a one-time $1,000 deposit from the Treasury. Additionally, U.S. citizens under 18 can receive up to $5,000 per year in supplemental contributions. Based on early CDC data indicating about 3.6 million births in 2025, the potential four-year cohort of 14.4 million children could generate $14.4 billion in initial deposits alone, not accounting for eligibility or participation rates. This sum represents roughly 9% of SPYM's stated $154.86 billion in assets as of July 1, 2026.
SPYM closed the abbreviated trading week at $87.67 on Thursday, July 2, slipping 0.11% but remaining 2.2% higher since June 26. Volume reached 15.69 million shares, about 21% above the recent 65-day average. U.S. markets were closed on Friday, July 3, for the Independence Day holiday, with NYSE and Nasdaq shut as part of the 2026 market calendar. The S&P 500 Index ended Thursday unchanged at 7,483.24, while the Nasdaq Composite fell 0.8% amid weakness in semiconductor stocks, and the Dow Jones Industrial Average rose 1.1% to a fresh record high.
State Street's data shows SPYM's assets under management jumped from $119.09 billion on March 31 to $154.86 billion by July 1, a gain of $35.77 billion or 30.0%. However, the share price appreciation from $76.54 to $87.75—a 14.6% increase—accounts for only about $17.4 billion of that growth. The remaining $18.3 billion came from net inflows, indicating strong investor interest beyond mere price gains. This disparity is significant for investors, as it suggests organic demand for the fund, likely driven by its role in the Trump Accounts program.
State Street Investment Management CEO Yie-Hsin Hung expressed enthusiasm over SPYM's selection, stating the firm is "thrilled that SPYM has been selected" and highlighting that the accounts are designed to help families "start early and stay invested over time." The fund's low expense ratio of 0.02%—the lowest among unlevered S&P 500 ETFs listed in the U.S.—is a key selling point. For comparison, the larger SPDR S&P 500 ETF Trust (NYSEARCA:SPY) charges 0.0945% and has a much higher trading volume. SPYM's 30-day average spread is 0.0127%, wider than SPY's 0.0021%, but its cost advantage makes it attractive for long-term holdings.
The Treasury Department has indicated that additional fund options, including iShares Core S&P 500 ETF (NYSEARCA:IVV), Vanguard Total Stock Market ETF (NYSEARCA:VTI), SPDR Portfolio S&P 1500 Composite Stock Market ETF (NYSEARCA:SPTM), and iShares Core S&P Total U.S. Stock Market ETF (NYSEARCA:ITOT), will be available in the coming months. Until the election tool is ready, all contributions will remain in the default SPYM fund, ensuring a steady stream of inflows for the near term.
SPYM's portfolio is heavily weighted toward technology, which constituted 36.87% of the fund as of July 2. Top holdings include Nvidia Corp (NASDAQ:NVDA), Apple Inc (NASDAQ:AAPL), Microsoft Corp (NASDAQ:MSFT), Amazon.com Inc (NASDAQ:AMZN), and Alphabet Inc Class A (NASDAQ:GOOGL). This concentration introduces sector risk, particularly if tech stocks face headwinds. Last week, chip stocks declined, with Nvidia falling 1.4% and the semiconductor index dropping 5.4%, as investors took profits after a strong year, according to Bruce Zaro, managing director at Granite Wealth Management.
Market participants are now focused on the Federal Reserve's June meeting minutes, due for release on Wednesday at 2 p.m. ET, seeking clues on interest rate policy under new Fed Chair Kevin Warsh. The June jobs report, which showed the U.S. economy added only 57,000 jobs versus the 110,000 expected, has eased pressure on the Fed to hike rates, as noted by Adam Sarhan, CEO at 50 Park Investments. Large-cap funds benefited from this data before the holiday.
Looking ahead, the launch of Trump Accounts could reshape ETF flow dynamics. Andy Blocker, head of policy and government relations at Edward Jones, told Reuters that the $1,000 minimum "removes the barrier of having nothing to start with," potentially attracting new investors. For SPYM, the combination of government backing and ultra-low fees positions it as a core holding for a new generation of savers, but investors should monitor the fund's tech-heavy exposure and the eventual expansion of fund choices.
